I have a 1998 ford explorer v6 sohc. The truck over heats but not all the time. I have replaced the thermastat and fan clutch. These did not solve the problem of over heating. I drove the truck without air conditions about 100 miles and was in stop and go traffic turned on the air condition on and it over heat in less than 2 minutes. I turned the air conditioning off and turned the heater on to cool down the engine.
What is causing this problem? I really don't want to keep change parts until the problem is solved. I was also told that the fan module may cause the engine to over heat.
Any help would be appreciated.

Mar 15, 2020 - Ok give me a minute to look it up. It is under the lower intake manifold. You have to remove that to replace the knock sensor. The block, you ...
If thie engine in your explorer is the v6 4.0 I found this information online - You are not supposed to need to replace the timing chain(s) on a 4.0L
SOHC V6. There are actually a total of FOUR, on this particular engine.
This is a job that I would NOT recommend anyone even thinking of
attempting to replace, if it's by anyone other than a FORD DEALER
TECHNICIAN FAMILIAR WITH DIASSEMBLY/ASSEMBLY OF 4.0L SOHC V6 ENGINES.
The reason for this is because, this particular engine is an interference engine BIG TIME!!! There are NO timing marks on this particular engine. They require FIVE dedicated Ford/Rotunda tools to service.
This vehicle shouldn't have a timing belt. Are you wanting to know about the timing chain? What engine size is it? It should be a 4.0 v6 but do you know if it is a OHV engine or a SOHC engine?
Yes. You should be able to replace it without removing the intake manifold. The bolts are very hard to reach, but it can be done with the proper set of sockets and universal joint extensions. I know it looks impossible. If in doubt, take it to a reputable repair shop. Don't let anybody charge you for intake manifold removal.
that is true your firing order is wrong here is a link to a web sight that has all the 1998 explorers 6cyl just click on the one that your explorer is and it'll show you the correct firing order also make sure you have your plugs gaped right good luck.

If this is a SOHC 4.0 V6 then there is a recall on the tensioners for the timing chain, they cause the kind of noise you speak of, check with ford, this is the SOHC only.
your transmission part number for a motocraft rebuilt trans would be TRM1341, as far as they list it the transmission was only for that year, meaning you would need to find another 1998 explorer or 1998 mercury mountaineer in order to replace your trans. hope this helps :)
